1 Product Description

1.1 Features of the TITANUS RACK·SENS® 1U air sampling smoke detection system

TITANUS RACK·SENS® 1U is the latest generation of the renowned WAGNER air sampling smoke detection systems. TITANUS RACK·SENS® 1U was specially developed for use in 19” server racks and control cabinets.

Sensitivity TITANUS RACK·SENS® response threshold can be set between 0.1 or 0.5 % and 2 %/ obs./m, depending on the design. The setting is adjusted at intervals of 0.1 % obs./m. Alarm forwarding is possible starting from 0.01% obs./m via an adjustable pre-warning threshold (10 – 80% of the main alarm threshold). An optional bar graph provides a display sensitiv-ity from 0.01% or 0.05% obs./m. The reliable High-Power-Light- Source in TITANUS systems ensures uniform response behaviour for different types of fires in accordance with EN54-7 and EN54-20.

Intelligent signal processing The TITANUS RACK·SENS® 1U features LOGIC·SENS, an intelligent

signal processing for avoiding false alarms. Complex algorithms based on numerous fire trials and decades of experience ensure a high level of safety in differentiating between a false alarm and a fire event.

Safe airflow monitoring PIPE·GUARD, the comprehensive package for airflow monitoring, de-

tects safely malfunctions breakdowns such as pipe breakages or blocked sampling holes. Airflow monitoring is temperature-compensated and can be set to be air pressure-dependent.

Plug and Play Installation and commissioning of the TITANUS RACK·SENS® 1U are simple with the Plug & Play function. The TITANUS RACK·SENS® 1U detection unit is pre-set for standard ap-plication usage. TITANUS RACK·SENS® 1U is immediately ready for op-eration once it has been connected to the mains or 24 V supply and is properly commissioned.


1 – 2 Data: 03/09 TRS_A_01-en-e

Networking If fitted with on optional network card, TITANUS RACK·SENS® 1U de-

vices can be linked together in an Ethernet network. From a central point the user can, for example, via VisuLAN T® monitor all connected units for smoke levels, airflow values etc. In addition, the TITANUS RACK·SENS®

1U can be integrated via the so-called OPC server into existing hazard and alert building management systems.

Potential free contacts TITANUS RACK·SENS® 1U provides potential-free contacts for “main

alarm” and “pre alarm”, “fault”, “service blocked” and “released” as well as for 5 programmable relays. The air sampling smoke detection system interfaces there for collective and addressable 0F

1 status signal easily with any type of central fire alarm system.

2. Detection- unit TITANUS RACK·SENS® 1U can be fitted with an optional second detec-

tor to perform as a double knock system. Each detection unit includes 2 alarm thresholds (pre-alarm and main alarm) and is provided with a sen-sibility of 0.1 or 0.5 % obs./m.

Shutdown In order to carry out an object shutdown (electrical disconnection) a po-tential-free relay contact is provided which can be cascaded with a high power relay for shut down of high power server racks. Object shutdown is essential to prevent potential re-ignition when a fire is being extinguished after extinguishing gas concentration has depleted below effective levels.

Diagnostics The optional DIAG 3 diagnostics device, provides quick and easy device configuration and visualisation during commissioning, inspection and ser-vicing. For diagnostics purposes events are stored in the TITANUS RACK·SENS® 1U.

Designing detection points The respective project planning instructions for object protection in this

manual must be complied with when planning the TITANUS RACK·SENS® 1U ® sampling points.

Patented detection points WAGNER’s patented aspiration reduction film sheets, clips and bande-

rols make assembly simple and comfortable and avoid whistling noises during operation. Another advantage is the quick and easy identification and monitoring of the aspiration sampling point diameters.

Options for extension and extension modules The TITANUS RACK·SENS® 1U system is modular configurable and of-

fers optional extensions such as a second air sampling smoke detector, temperature indication, smoke level bar graph, mains and emergency power supply as well as integrated extinguishing systems in the compact 19-inch 2U design. TITANUS RACK·SENS® 1U offers highly flexible op-tions for extension in the form of shutdown modules and extin-guisher/shutdown modules as well as external extinguishing cylinders.

Comprehensive

accessories The comprehensive assortment of accessories ranging from pipe com-ponents and network cards through to optical alarm indicators enables the TITANUS air sampling smoke detection system to be adapted per-fectly to the application in question.

Temperature monitoring Up to 5 external temperature sensors can be installed as part of the op-

tional temperature module. These sensors can be placed anywhere within the monitored area. Temperature alarms are adjustable and, with the aid of programmable relays, allow appropriate counteractive meas-ures to be implemented if necessary.

Programmable

relays The 5 programmable relays enable specific action to be taken in the case of specific events. This could be the forwarding of a temperature alarm from the optional temperature module.

1.2 Areas of Application

TITANUS RACK·SENS® 1U is a fire protection system to protect servers and control cabinets in 19” format. Due to its specific characteristics, TITANUS RACK·SENS® 1U is particu-larly suitable for use in 19″ racks when: • Fires need to be detected as early as possible in order to initiate

counteractive measures and/or automatic shutdown, • False alarms must be avoided, • Only 1 height unit of space is available for the fire protection system, • High to very high air speeds are present, • A staged alarm concept needs to be implemented.

Object protection TITANUS RACK·SENS® 1U is especially suited to monitor non-ventilated, forced-air cooled and air conditioned equipment/ cabinets such as:

EDP cabinets, server racks and network cabinets, the basic hardware/software equipment to provide data processing and storing

Telecommunication racks, vital for linking to the rest of the world using modern communication tech-nology

Production control cabinets which manage all manufacturing processes

Distribution, emergency power supply and other control cabinets, which ensure a company’s steady power supply to systems (light, air-conditioning, etc.)


TRS_A_01-en-e Data: 03/09 1 – 5

Air samples are taken from the monitored cabinets (see fig. 1.1) via a pi-pe system with pre-defined aspiration sampling points. The samples are analysed for smoke by the TITANUS RACK·SENS® 1U. Staged alarm concepts can be easily implemented by using user selectable pre- and main alarm thresholds.

Air flow monitoring An air flow sensor checks the connected pipe system for breaks and blo-ckages.

The airflow monitoring is temperature-compensated and can be config-ured air pressure-dependent. After an adjustable fault delay period finishes, the fault is displayed on the front panel and, if connected to a fire alarm system, an appropriate signal is forwarded to the fire alarm system via a potential-free contact. The basic signal process in the air flow sensor is shown in Fig. 2.3.

Common fault( Fault ) Active detector, network or battery-faults generate a common fault mes-sage, which is displayed by a “Fault” LED on the front panel. The fault can be forwarded via a potential-free contact to a fire alarm system, for instance. Further fault information details will be provided by the DIAG 3 diagnostics tool.

Other fault messages* A separate LED is provided for the following fault signals:

Battery fault (Battery) Mains fault ( Mains)

Status signals

Service / blocked Blocking of extinguisher activation by the door contact switch or in ser-vice mode by activating the key-operated switch.

Released The red LED “Released” serves two functions. Firstly it flashes once an optional electrical shutdown process has been initiated and secondly it will be permanently on if an optionally connected TITANUS RACK·SENS® extinguishing systems has been set off (discharge of ex-tinguishing agent).

Bargraph* The current smoke level in the detection unit is displayed by a ten-digit bargraph display.

TRS_A_02-en-e Data: 03/09 2 – 5

Operating mode indicator The TITANUS RACK·SENS® 1U operating mode indicator is continually

lit up during normal operation. The operating mode indicator flashes in the event of data transmission for fault diagnostics in the DIAG 3 via the infrared diagnostics interface as well as when air flow is initiated.

Indicators for * pre- and main alarm Each detector unit has a pre-alarm and main alarm indicator. If 2 detec-

tion units are installed, these are automatically linked together as a dou-ble knock system ( 2 detector coincidence detection). This means that if both indicators display main alarm, this could optionally lead to a shut-down of external equipment, or activate the extinguishing system after a pre-warning period.

Alarm lamp The alarm lamp is a large-surfaced, highly visible indicator light for the main alarm.

Sensor indicator* The sensor indicator consists of a vertical array of five LED indicators (numbered from 1 to 5) and shows which sensor of the maximum of 5 connectable temperature sensors is in alarm status. You will find further information on this in the description of the “Config/Temp” button.

Temperature indicator * This 2-digit 7-segment indicator displays the current temperature for the connected temperature sensors in ºC. The “Config/Temp” button enables the current temperature readings to be shown for all sensors.

„Config / Temp“ button The “Config / Temp” button provides dual functionality. On the one hand it allows to eliminate ( disable ) faulty or detached bus modules such as extinguishing-/shutdown or just shutdown modules. On the other hand individual temperature readings of up to five connected temperature sen-sors can be selected by this button.

Reset/ Buzzer Off button The TITANUS RACK·SENS® 1U device has a reset button on the front of

the base device to reset alarm and fault indicators. This button enables the alarm and fault signals to be reset once the cause has been elimi-nated. The internal buzzer can also be switched off using this button.

Key-operated switch Off/Service/On The key-operated switch enables the device to be turned on and off and

switched to service mode for maintenance purposes.

Network Several TITANUS RACK·SENS® 1U devices can optionally be connected to a network. This network system enables the user to monitor status messages in all connected TITANUS RACK·SENS® 1U devices. In doing so, all proc-esses for aspects such as smoke levels, air flow values and alarm and fault statuses are transmitted via the bus system. The visualisation software VisuLAN-T and an associated TITANUS RACK·SENS® 1U network module are required to operate TITANUS RACK·SENS® 1U in a network and are available as an option.

1. OFF 2. ON/Service 3. ON/operational In Service-Mode all fault and alarm relays will be deactivated (isolated). No alarm or fault signals will be forwarded to the fire panel. This opera-tion mode is flagged up by the service/blocked relay contact output. This contact will also be activated if one of the door contact switches is not closed (door open). This contact output (Service) is to be seen as an additional fault signal. For a proper installation this contact needs to be forwarded to a fire panel. In order to save the additionally required input line at the fire panel, an alternative wiring scheme is provided in chapter 5.

Blockage Extinguishing is blocked/disabled when a door is opened. Note, that ob-ject shutdown is independent of this and will take place when key switch is “ON” and a main alarm is present. The following table shows depending on key switch and door contact conditions when shutdown or extinguishing is enabled or disabled.

If the unit is set to key switch position “ON”, activation of the manual re-lease will result in an immediate discharge of extinguish ant and can only be disabled via the door contact switches (release blocked). Once extin-guishing has been activated, it cannot be stopped.

Before re-enabling extinguishing via key switch activation, all alarms must have cleared out and the manual release must be reset!

Device fault If the fault indicator lights up, a trained employee or WAGNER service must be informed.

In the event of fire Detection unit 1 and detection unit 2 (according to selected options) detect smoke fumes and activate alarm.

The internal buzzer sounds. The large red “alarm lamp” indicator flashes. The TITANUS RACK·SENS® 1U can carry out control functions such as shutting down cabinet fans via the 5 user programmable relays (only 24 V fans, otherwise through auxiliary relays).

If necessary, the TITANUS RACK·SENS® 1U will control the shutdown of the electronics cabinets being monitored via the external shutdown module.

Extinguishing will take place after a main alarm was triggered plus a maximum time of 60 sec. pre-warning time. LED “Extinguishing release” flashes during pre-warning time and will be permanently on thereafter.

Please note, that if the protected objected was not disconnected from its power source when a fire incident was detected, it is possible, that the fire may re-ignite due to loss of extinguishing agent concentration after discharge.

2.3 Pipe system

The pipe system serves to take representative air samples from the pro-tected area. TITANUS RACK·SENS® 1U systems are preferably inte-grated into the cabinet in order to keep the sampling system as simple as possible. Cabinets with re-circulated air can be monitored with a so-called standard sampling pipe with a single aspiration hole. Cabinets with several air outlets must be equipped with individually configured pipe sys-tem.

The standard sampling pipe type AP-1 is especially designed for cabinets cooled by re-circulated air. As any possible smoke fumes are evenly dis-tributed in such cabinets, this standard sampling pipe can be used here in order to save on installation expenses for a conventional pipe system. By installing in the TITANUS RACK·SENS® 1U uppermost rack, the unit should be cable to detect smoke, even in a case when ventilation fails as smoke will typically climb upwards in the event of fire.

4.4 General pipe system project planning

4.4.1 Pipe system configurations

When planning the pipe system, it must be ensured that reliable fire dete-ction is guaranteed for any fire present in an installation or in a monitored area. The number of sampling holes and the pipe system layout depends on the size, ventilation and shape of the monitored area. The pipe system is to be fitted in accordance with the project planning guidelines in this sec-tion while taking into consideration the following points:

Symmetrical design The pipe system shall preferably be designed to be symmetrical, i.e.: equal number of sampling holes per pipe branch equal lengths of pipeline (must not exceed ± 30 % deviation) Equal distances between adjacent sampling holes in sampling pipe (do not exceed deviation of ±30%)

Similar air pressure conditions along the sampling pipe If air outlets located at cabinet doors are to be monitored, then it is ad-vised to use short, flexible tube interconnections (max. length 30 cm)

The pipe system is should be constructed with rigged pipe. Flexible tube interconnections are only to be used as an exception. This is due to possible air flow changes once the tube is moved.

Please keep the length of tube interconnections as short as possible.

Asymmetrical design If the pipe system must be laid out asymmetrically due to structural con-straints, the following specifications apply:

The number of sampling holes as well as the length of the shortest and longest pipe branch in the pipe system must not exceed a quantity or length ratio of 1:2.

The distances between adjacent sampling holes in the sampling pipe must be equal (do not exceed deviation of ±20%).

The diameters of the sampling vents are determined for each pipeline branch individually and depend on the number of sampling vents on the pipeline branch in question.

Branch length In order to ensure that smoke aerosols are transported quickly through the sampling pipe and to ensure fast detection, it is better to plan several shorter branches than a few long ones (preferably a “double U-shape pi-pe system” instead of a “I or U shape pipe system”).


TRS_A_04-en-e Data: 03/09 4 – 15

Pipe designs 4 types of pipe layouts can be used depending on the cabinet geometry (see Fig. 4.12).

I- pipe An air sampling smoke detection pipe system without branches.

U- pipe An air sampling smoke detection pipe system which branches into 2 air sampling branches after the connection to the TITANUS RACK·SENS® 1U.

M-pipe An air sampling smoke detection pipe system which branches into 3 air sampling branches after the connection to the TITANUS RACK·SENS® 1U.

4 – 16 Data: 03/09 TRS_A_04-en-e

Direction change 90° angles and bends (elbows) increase flow resistance. They are there-fore to be avoided as much as possible. 90° swept bends should preferably be used, as 90° elbows have a high flow resistance. So 90° elbows should only be used where they cannot be avoided because of structural restrictions. equivalent straight pipe length

90° elbow 1,5 m

90° swept bend 0,3 m

If 90° elbows or swept bends are used, the maximum overall length of the pipe system is reduced. 90° swept bends are to be preferred over 90° elbows. Too many changes in direction will seriously influence the detection time.

Special cases If because of structural restrictions the pipe system does not correspond to the design guidelines given here, each case must be calculated sepa-rately by WAGNER.

Checking In critical applications, check there is safe detection by carrying out simu-lated smoke tests (see chapter 7.5). Check also for proper suction pres-sure at the individual aspiration holes.

To increase the transport speed in the pipe system in critical areas, the fan voltage can be raised in steps from 9 V (Standard) to 13.5V.

4.4.2 Sensitivity

According to EN 54-20, the sensitivity of a air sampling smoke detection system can be divided into particular fire sensitivity classes. These sensi-tivity classes describe particular example applications in which the sys-tems can be used. Permissible system project planning can be deter-mined for each classification according to Chapter 4.2. Air sampling smoke detection systems with a higher sensitivity class ac-cording to EN 54-20 also meet the requirements of the lower classes.

Class Description Example application

A Air sampling smoke de-

tector with very high sensitivity

Very early detection: Highly diluted smoke in air

conditioned IT areas

B

Air sampling smoke de-

tector with increased sensitivity

Early detection: Diluted smoke in conventional

cooled IT areas.

C Air sampling smoke de-

tector with standard sensitivity

Standard detection: Fire detection with the benefits of air sampling smoke detection systems

The fire sensitivity classes A, B and C can be achieved with each de-tector module available, depending on the number of aspiration aper-tures.

Up to 5 external temperature sensors type TS-1 can be installed as part of the temperature module. These can be attached to the components being monitored with cable straps or adhesive pads. Via the diagnostics tool alarm thresholds can be set for individual tem-perature alarms and forwarded via the programmable relay contacts. The settings via the diagnostics tool are described in more detail in the com-missioning chapter.

4.6 Device shutdown

The extension module type SU-1 enables external equipment to be shut down via a type SR-1 shutdown relay. Equipment with a power rating of up to 400 W for inductive loads and up to 2,000 W for resistive loads can be shut down via the relay contact. A suitable high power relay should be activated via the shutdown relay for equipment with higher power consumptions. Schematics for the shut-down relay and the high power relay is described in more detail in section 5.2.12 or 5.2.13 “Installation / TITANUS RACK·SENS® 1U device shut-down“.

4.7 Door contact switch

Cabinet doors can be monitored with door contact switches for supervi-sion. This is especially required if the TITANUS RACK·SENS® 1U is trig-gering an optional extinguishing system. Door contact switches are to be positioned in such a way that the switch is activated when the door is closed and the contact is closed. If the door is opened, the contact in the switch opens and the TITANUS RACK·SENS® 1U device is blocked. Af-ter a delay of 10 seconds, the TITANUS RACK·SENS® 1U device indi-cates a fault. If several door contact switches are connected to the door contact input, they are to be connected in series, so that the TITANUS RACK·SENS® 1U device is interrupted at the door contact switch input if only one of the doors is opened.

4.8 Air flow monitoring

EN54-20 requires detection of a 20% airflow volume deviation. In order to accomplish this, the airflow threshold must be set to ≤ 20 %.At this point it is recommended to perform an air-pressure dependent airflow initialisa-tion adjustment. For installations not complying with EN-54-20 the airflow threshold can be set as desired. The airflow monitoring of the connected pipe work must comply with na-tional directives.

Adjusting airflow sensitivity The airflow monitoring sensitivity must be chosen according to the appli-

cation. Pipe rupture or blockage have to be detected safely. If a different airflow monitoring sensitivity than 20% is required, the diagnostics tool needs to be used for setup.

Dynamic air flow sensor technology The integrated air flow monitoring enables the system to detect both pipe

breakages or sudden blockage (e.g. in the event of sabotage in the pipe system). As the dynamic air flow sensors are only active if the “Dynamic air flow ON” settings are programmed in the software when the device is put into operation, the following aspects must be taken into account.

• Dynamic airflow monitoring is usually not suitable for monitoring of cabinets with forced airflow, as the systems will respond in this op-eration mode to small airflow variations.

The following limits must always be complied with for the TITANUS RACK·SENS® 1U system: • The minimum pipe length between 2 aspiration holes is 0.1 m. • The maximum pipe length between 2 aspiration holes is 4 m. • The maximum monitoring surface area per aspiration holes

corresponds to the monitoring area of a point-detector according to the regulations in the particular national standards.

• Maximum 10 aspiration holes are possible TP4F

5PT.

Because of country-specific regulations, there may be restrictions compared to the design limits in this manual!

4.8.1 General project planning instructions for shutdown and cooling Shutdown

Shutdown For electrical shutdown of racks or external equipment, please pay atten-

tion to the following issues:

• If complete units/racks are disconnected from power by shutdown, make sure that sufficient cooling is provided.

• The shutdown process should be carried out in a proper way, by means of a controlled shutdown with no damages to equipment and no loss of important data (i.e. soft-shutdown, save data, use an es-tablished shutdown procedure provided by the owner/user).

• Some types of racks will automatically open their doors when dis-connected from power. In this case extinguishing is blocked by door contacts.

• Therefore it is essential that for successful extinguishing the doors stay closed during shutdown.

Cooling When using TITANUS RACK·SENS ® 1U in racks with forced airflow the following points need to be considered:

• Cooling of the rack and its components must not be impaired by in-stalling the TITANUS RACK·SENS ® 1U unit and its components.

• In case of power disconnection (shutdown) of the rack and its com-ponents the minimum required cooling requirements must be pre-served.

4.10 Calculating detection sensitivity

Selecting the sensitivity on the TITANUS RACK·SENS® 1U detection unit must be carried and in such a way that the desired sensitivity will be achieved at the individual detection points (smoke aspiration holes). This can be calculated by multiplying the detector sensitivity with the number of all smoke aspiration holes designed for the system.

DPprojRACKSENSDP NSS .×=

S BDPB = Sensitivity of a individual detection point

S BRACKSENS = Selected detector sensitivity for the TITANUS RACK·SENS® 1U

NBproj. DPB = Number of all detection points in the system

Project planning for an area to be monitored is always carried out accord-ing to specifications for point type smoke detectors. For cabinet monitor-ing at least one or two aspiration holes need to be provided per cabinet. When several areas are monitored using an aspirating smoke detection system, it must be ensured that the overall sensitivity of the aspiration apertures is ≤ 3.5 %/m light obscuration within a closed area. If this value is not reached, the sensitivity must be set higher.

4.11 Power Supply

4.11.1 Calculating capacity for external power supply

The alarm-ready status in the fire protection system and the event of an emergency are taken into account when rating the external power supply.

The minimum supply current in the power supply unit must be calculated in such a way that the system’s full functioning capacity is guaranteed by the power supply unit in itself. In case of alarm the current is calculated by the following formula:

Supply current ingChAlarmtotTot III arg.. +=

PSUTot II =.

ITot = Total current for all operating devices in [A]

IAlarmtot = Alarm current in all TITANUS RACK·SENS® devices in [A]

5.2.13 Installation and connection for device shutdown (high power)

In the event of fire detection, the shutdown module connected to the TITANUS RACK·SENS® 1U device shuts down external equipment via a shutdown relay or high power relay. In the event of a shutdown, the backup power is removed from an incipient fire and thus prevents the fire from spreading further. 1. Install the shutdown relay and the high power relay, if there is one,

on a DIN-rail in such a way that you can wire it without any prob-lems.

2. Now connect the components in accordance with the following con-nection diagram.

TITANUS RACK·SENS® 1U Installation Pipe System

TRS_A_06-en-e Data: 03/09 6 – 1

6 Installation of the Pipe System

The pipes and fittings used for the pipe system must always meet re-quirements for Class 1131 in accordance with EN 61386-1, 2004.

Class 1131 puts the following requirements on the pipe system used:

characteristics severity code

compression resistance 125 N

impingement resistance 0,5 kg, drop height at 100 mm

temperature range -15 °C to +60 °C

In principle, the following pipes as well as the related fittings are to be used in configuring the pipe system:

external diameter internal diameter

ABS PVC

air sampling pipe 25 mm 21,4 mm 21,2 mm

Take note of the temperature range specified in the “Technical data” chapter under “3.3 Pipe system” when configuring the pipe system.

ATTENTION

Installation Pipe System TITANUS RACK·SENS® 1HE

6 – 2 Data: 03/09 TRS_A_06-en-e

When installing TITANUS RACK·SENS®1U and its components, special attention must be paid to avoid damaging them through dropping tools or installation material! Cooling of the rack and its components must not be impaired due to in-stallation of the TITANUS RACK·SENS® 1U unit and its components.

Installation Instructions The pipe system must be designed according to the requirements of the project and the pipe design guidelines (see chapter 4 "Pipe Design").

1. Cut the pipes with a pipe cutter or a metal saw. Chips must be re-moved and rough edges trimmed.

2. Before gluing, remove any dirt and grease from the joints with the rec-ommended cleaning agent. Glue the pipe ends to the corresponding fittings so that they are airtight.

3. Keep the pipe lengths and direction changes to a minimum. Elbows and bends have an extremely high flow resistance. Use them only where this is unavoidable. Should this be necessary, the pipe length must then be reduced in relation to the fitted bends 0F

1.

Sweep elbows should be used instead of elbows. If there are too many direction changes, an air flow fault can occur in TITANUS RACK·SENS® 1U and detection time can be affected.

4. The pipes must be installed in such a way that they do not sag or move. They should be fixed with pipe clips without rubber core. The space between the pipe clips should be no more than 80cm. Reduce the space between clips to no more than 30cm if there are high tem-perature variations.

1 An arc equals a straight piece of pipe of 0.3m an elbow equals a straight piece of pipe of 1.5m

ATTENTION

INSTRUCTION


TRS_A_06-en-e Data: 03/09 6 – 3

Do not use pipe clips with rubber cores as these do not expand length-wise and the pipes would sag or crack.

5. Close open pipe ends with an end cap.

After pipe installation is complete, check for the following: - air tightness (eg due to damage) - any faulty connections - correct design of the air sampling holes

Pipe Clips As a rule, plastic pipe clips, type 23, are used for the installation of pipe systems (∅ 25mm). They do not allow for linear expansion and in areas with high temperature variations the plastic pipe shells, type CLIC-PA must be used. (see fig. 6.1).

Ensure that all mechanical work (i.e. drilling of aspiration holes etc.) is carried outside of the cabinet.

Bore Holes 1. Drill a hole with a 10mm drill at a right angle to the pipe. 2. Carefully de-burr the holes. 3. Clean the area around the hole (around the whole pipe) from dirt and

clean with Tangit cleaner. 4. Select the size of the aspiration-reducing film sheet according to the

pipe design guidelines 5. Stick the aspiration-reducing film sheet over the hole

(see fig. 6.3, 1 ). 6. Prevent the film sheet from coming loose by sticking marking tape

over it (see fig. 6.3, 2 ).

The holes in the aspiration-reducing film sheet and the marking tape must be placed exactly over the bore holes. The perforations in the aspi-ration-reducing film sheet must not be altered.

To keep the surface of the film sheet dust and grease free, avoid any contact.

TITANUS RACK·SENS® 1U Commissioning

TRS_A_07-en-e Data: 03/09 7 – 1

7 Commissioning After the TITANUS RACK·SENS® 1U device and its components have been fully installed, the device can be put into operation.

7.1 Operating TITANUS RACK·SENS® 1U

7.1.1 Key switch

The TITANUS RACK·SENS® 1U can be operated in different operating modes using the key switch.

ON: In this switch setting the TITANUS RACK·SENS® 1U system is ready for operation. In this mode, alarms and fault signals are forwarded to an op-tional connected fire alarm system. In the event of a main alarm, a con-nected shutdown module can also be activated.

Service: In this switch setting the TITANUS RACK·SENS® 1U system is isolated from the fire alarm line. In the event of a main alarm, forwarding of alarms and fault signals to an optional connected fire alarm system likewise elec-trical shutdown or extinguishing will be disabled.

Off: In this switch setting the TITANUS RACK·SENS® 1U system is switched off.

7.1.2 Config. Temp. button

The „Config. Temp.“ button features a dual functionality.

On the one hand it provides selection and display (in __ °C) for all physi-cally connected temperature sensors (only available with optional tem-perature module).

On the other hand a given configuration for a TITANUS RACK·SENS® 1U can be “featured down”. This can be useful in cases where modules have to be removed from the system configuration such as: - in a fault condition (i.e. defective shutdown module ). There may be a

request, that the device must be operational without faults. (A defec-tive module as well as a removed module will cause a fault, since it was added automatically to the system configuration during installa-tion and power up.)

- after a module was exchanged. In this case the defective module needs to be removed from the system configuration. New modules will be detected and added to the system configuration automatically.

Commissioning TITANUS RACK·SENS® 1U

7 – 2 Data: 03/09 TRS_A_07-en-e

Removing active modules (i.e. extinguishing-shutdown modules) will u-sually lead to a reduced functionality of the fire protection system and possibly to a loss of fire protection altogether. A defective module must be replaced immediately.

A defective module can be removed from the system configuration by us-ing the „Config.“ button as follows: - Put the key switch in position „Service“. - Press „Config.“ button for 10 seconds.

The device will perform a LED- and buzzer test. System configuration mode is indicated by the service / blocked and fault LED-symbols which are flashing simultaneously. If the optional temperature module is installed, the associated display will show in this special case the number of connected extinguishing-/shutdown modules. Regardless of the presence availability of the temperature module, the device will be now in configuration mode.

- By pressing again the „Config.“ button for another 10 seconds, the actual system configuration will be updated and stored. The device is confirming the update with three beeps by the internal buzzer. The service/blocked indicator will stop flashing and be continuously on.

- Alternatively by pressing the „Reset“ button or by putting the key-switch into the “ON” position, the actual system configuration will be ignored. In this case the device will show a fault when switched to the „On“ position since the defective module was not removed from the system configuration.

Display of connected temperature sensors and modules is only available with an installed temperature module. Removing modules from the sys-tem configuration is still possible without this temperature module, but displaying the number of connected modules is not available. An actual system configuration can be checked via the diagnostics tool DIAG 3.

7.1.3 Reset and buzzer off button

This button enables alarms and faults to be reset when the TITANUS RACK·SENS® 1U device is in service mode if the event which caused it is no longer present. To do so, the key switch must be switched to the “Service” position and the “Config.” button be held down for about 3 seco-nds.

In normal operating mode the TITANUS RACK·SENS® 1U internal buzzer can be switched off using this switch. The buzzer will come back on for each new fault or each new alarm which occurs. The buzzer is reset by pressing the button.

7.2.2 Commissioning procedure

Laptop or DIAG 3 diagnostics tool is not required for standard commis-sioning default settings will not be changed. 1. Switch on the supply voltage.

2. Switch the key switch on the front of the TITANUS RACK·SENS® 1U

device to the “Service” position.

3. Now press the “Config” and “Reset” buttons on the front of the TITANUS RACK·SENS® 1U device at the same time to initialise the air flow. Air flow initialisation will now take place automatically.


7 – 6 Data: 03/09 TRS_A_07-en-e

The green operation mode indicator will flash while the TITANUS RACK·SENS® 1U is initialising. If initialisation is completed, the operation mode indicator will light up continuously.

Air flow initialisation can take up to 2 hours. It is successfully completed when a constant air flow has been attained in the TITANUS RACK·SENS® 1U

The air flow in the TITANUS RACK·SENS® 1U should not be altered dur-ing the initialisation phase.

In a normal situation the TITANUS RACK·SENS® 1U should now run without any problems. If this is not the case, follow the procedures de-scribed in section 8.2 (Procedure in the event of a fault). 4. If no faults or alarms are shown on the TITANUS RACK·SENS® 1U

display, you can now switch the key-operated switch on the front of the TITANUS RACK·SENS® 1U device to the “On” position.

5. The device is now ready for operation and is no longer isolated from the fire alarm line. Alarms and fault signals will now be forwarded to an optional associated fire alarm system. Likewise in the event of an alarm, an optionally connected relay (via shutdown module) will be energised for electrical shutdown and, if not blocked/inhibited by an door contact, an optionally connected extinguishing systems will be activated.

A basic device test is possible using the diagnostics tool. With its mes-sage and status readouts, the diagnosis programme facilitates consid-erably simplified servicing. The DIAG 3 can be attached to the TITANUS RACK·SENS® 1U using a device mount or be kept up to 3 m away along a straight line (±10°) from the infrared interface.

Data is read via an infrared interface on the TITANUS RACK·SENS® 1U using the DIAG 3, which is linked to the PC with a USB cable.

Since the infrared interface provides reception and transmission within a range of 3 meters, several adjacent installed TITANUS RACK·SENS® 1U units may appear in the device selection window (DIAG 3). Each one can be addressed separately.

Diagnostics tool commissioning is described in the section 7 “Commis-sioning”.

7.4 Testing the detection unit and alarm forwarding

In the order to check alarm forwarding it is absolutely essential to block the TITANUS RACK·SENS® 1HE via door contact switch (door open). In case of an implemented shutdown relay you MUST DISCONNECT THE RELAY

If LOGIC·SENS is set to “ON” on the diagnostics tool “Settings” screen (see section 7.2.1.7 “Settings”), it should be set to “Off” during the alarm testing with the test aerosol in order to speed up alarm evaluation.

Pull out the TITANUS RACK·SENS® device and check alarm forwarding to the fire alarm system in the following way: 1. Open at least one door of the associated monitored doors in order to

block any connected extinguishing systems. 2. In case of an implemented shutdown relay, disconnect the relay. 3. Spray the test aerosol into the first aspiration hole or into the test

adapter in the TITANUS RACK·SENS® 1U pipe system. 4. Proceed according to the table below.

Check whether... If this is not the case....

the alarm is displayed in the air sampling

smoke detection system.

1. check whether the display panel board is connected.

2. there is a defect in the air sampling smoke detection system.

the alarm is forwarded to the fire alarm

system and is signalled on its respective

line.

1. check the signal paths.

5. Wait until the smoke level has come down and all alarms have

cleared off. 6. Do not close the doors, before all alarms have cleared out and the

TITANUS RACK·SENS® 1U has been reset.

Record all test data in the test log in the appendix.

7.5 Testing response behaviour in cabinets

The TITANUS RACK·SENS® 1U system must be switched to service mode for the following tests.

Ensure, that the TITANUS RACK·SENS® 1U unit will only be set to “ON” after the test, if all alarms have cleared out.

The PYS 100 pyrolysis system determines fire alarm system response behaviour, especially for highly sensitive air sampling smoke detection systems. The pyrolysis system is designed to simulate an electric fire in a compressed time period through a reproducible smoke test.

The system generates defined quantities of pyrolysis particles and smoke to be reproduced under the same ambient conditions, so that changes in the response behaviour of the fire alarm system can be detected when the test is repeated.

• Pyrolysis phase when invisible smoke particles are released.

• Smouldering fire stage when visible smoke particles are released in quantities which match the response sensitivity required by system design.

The pyrolysis box is kept closed when operating in difficult-to-access in-stallations such as control cabinets as well as false floors and cable con-duits. The pyrolysis particles produced are then fed in a tube into the cabinet being monitored.

7.6 Testing air flow monitoring

The following steps can only be carried out after air flow adjustment is completed in accordance with section 7.3 “Air flow sensor adjustment".

Before checking the airflow monitoring set the key switch into “Service” mode to avoid forwarding of alarms and faults to a possibly connected fire and alarm panel.

Pipe breaks Test that a pipe break will be detected: 1. Loosen the pipe at the connection to the TITANUS RACK·SENS® 1U

or open the test adapter. 2. Check whether the fault display on the aspirating smoke detector is

flashing. 3. Check the air flow sensor data using the DIAG 3 diagnosis tool and a

PC or laptop. 4. Enter the result in the test record (appendix).

Blockage Test that a blockage will be detected: 1. Close all aspiration holes. 2. Check whether the fault display on the aspirating smoke detector is

flashing. 3. Check the air flow sensor data using the DIAG 3 diagnosis tool and a

PC or laptop. 4. Enter the results for the corresponding closed aspiration holes in the

test record (appendix).

Trouble shooting If air flow faults are not correctly recognised by the device, proceed as follows:

Check whether ... 1. All holes are free. 2. The pipe system has any breaks or cracks. 3. All pipe connections are sealed. 4. The fan can blow freely. 5. The correct aspiration reduction films have been used.

If no defects are identified, the TITANUS RACK·SENS® 1U device or the air flow sensor’s operational capability should be checked using a test pipe or diagnostics software. If airflow monitoring test is completed, set the key switch into position “ON”.

Ensure that no alarms and faults are present at this time.

8 Maintenance

8.1 Procedure for servicing If servicing or an inspection is carried out on the TITANUS RACK·SENS® 1U device, the key-operated switch on the front of the TITANUS RACK·SENS® 1U device should be switched to the “Service” position within 10 seconds for a system with monitored cabinet doors. If not, a fault will be released. In the “Service” setting, forwarding of alarms and fault signals as well as any optional associated shutdown or fire alarm system will be disabled.

Before the TITANUS RACK·SENS® is switched to the “On” operating mode again, alarms or faults must no longer be present as otherwise shutdown will be set off immediately after changing the switch position.

8 – 2 Data: 03/09 TRS_A_08-en-e

8.2 Trouble shooting

If fault messages appear on the TITANUS RACK·SENS® 1U, proceed as follows: 1. Open the cabinet door of the monitored cabinet and

switch the key-operated switch on the front of the TITANUS RACK·SENS® 1U device to the “Service” posi-tion within 10 seconds.

2. Look to see which fault indicator is displayed on the front of the TITANUS RACK·SENS® 1U device.

3. If the TITANUS RACK·SENS® 1U has an internal power supply unit and the “Mains” fault indicator is lit up, check the power connection to the power input module.

4. If the “Battery” fault indicator lights up, check the con-nection from the internal battery to the charge controller. If the connection to the charge controller is OK, replace the TITANUS RACK·SENS® 1U battery.

5.

If the “Fault” common fault LED lights up, a number of reasons could be behind such a fault indication. First of all, look to see whether there is a fault in one of the con-nected extension modules.

6. If this is the case, then the fault is with the extension module.

7. If this is not the case, the cause of the fault is in the TITANUS RACK·SENS® 1U.

8. If you have now identified the device or an extension module as the cause of the fault, check connections to all connected components such as temperature sen-sors, door contact switches, the shutdown module and shutdown relay are in working order.

9. If you locate the source of the fault and were able to eli-minate it, reset the device using the reset button on the front of the device. This should be done as the “Save fault” may be switched on via the diagnostics tool and the fault is displayed on the front, even though the cause of the fault has been eliminated.

10. If a fault is still indicated, then use the DIAG 3 diagnos-tics tool to further diagnostics the fault and follow the in-structions in the troubleshooting help topics.

If the fault could not be eliminated after carrying out the indicated instruc-tions, save the active diagnostics data.

Contact WAGNER Group GmbH and provide a detailed description of the fault as well as the saved diagnostics data (File type x.di3).

TRS_A_08-en-e Data: 03/09 8 – 7

8.7 Checking the air flow sensor adjustment

Check the air flow sensor value with the diagnostics software.

Operating principle During initialisation, the device first stores the measured actual value of the air flow as set point, via integrated air flow monitoring. This set point thereafter serves as the reference value for further evaluation of any air flow fault. Depending on the air flow threshold selected (see Chapter 4.3, section on Adjusting Air Flow Sensitivity), the current air flow value can vary more or less around this set point during operation, without trigger-ing an air flow fault. Only if the air flow threshold selected is exceeded the air flow fault signalled by the device will be forwarded.

Checking the actual value The tolerance range for the air flow threshold selected as well as the actual and set points are shown in the diagnostics software. The limits correspond to the air flow range set. Check the deviation between the actual value and the set point. If there is a deviation of 75% (taking into account the service interval) from the pre-set threshold, you should carry out a prophylactic test on the pipe system (see the paragraph on “Air flow fault elimination”)

The current air flow value may not only deviate from the set point just because of a fault in the pipe system (break or blockage) but also because of air pressure variations in the environment.

Troubleshooting an air flow fault If air flow adjustment has been carried out air pressure dependent and

the actual value is still not within the preset air flow threshold tolerance range (air flow fault is displayed on the device), another problem besides an air pressure or temperature variation may be present.

1. In such a case, check the pipe system is air-tight and not blocked (see section 7.6).

If the pipe network was changed during troubleshooting, the original pipe system layout must be restored afterwards and the air flow must be re-initialised.

2. If this inspection does not flag up a problem, check the air flow moni-

toring system by attaching the test pipe and carrying out the func-tional test described in section 7.8.2.

INSTRUCTION

INSTRUCTION


8 – 8 Data: 03/09 TRS_A_08-en-e

If the airflow monitoring unit is suspected to be faulty, the TITANUS RACK·SENS® 1U unit needs to be returned to WAGNER Group GmbH for repair.

If no deviations are detected in the process described during the functional test, this confirms there is no defect in the air flow monitor-ing system.

3. Carry out the adjustment process again with the connected pipe sys-tem.

It is essential to record the adjustment type (air-pressure-dependent or non-dependent) in the test log along with the air pressure and height above sea level if required.

4. Monitor the actual air flow value during routine servicing or check it

during the next inspection at the latest.

All stored and actual device data as well as settings made using the di-agnostics tool can be saved by the diagnostics software, or printed out or saved as a log.

5. If there is a similar set point deviation as before, unfavourable envi-ronmental factors are the cause for this deviation. If such negative influences to the air flow monitoring system cannot be eliminated, the air flow range should be enlarged.

ATTENTION

INSTRUCTION

TIP


TRS_A_08-en-e Data: 03/09 8 – 9

8.8 Checking the detector status

Check the detection unit data with the diagnostics software. Contamination in the detection unit or the sampled air is displayed in a bar graph and as a percentage. The blue bar in the graph shows the current level of contamination. This value is also given as a percentage underneath the graph. A value of 0% corresponds to the detection unit as new in clean ambient air. If the de-tection unit reading goes outside the permitted range (±100 %), there is a fault in the detection unit. The blue bar will then be outside the permit-ted range, which is highlighted in yellow in the bar graph. Small devia-tions are acceptable. Such deviations may appear due to contamination (e.g. dust) in the air sampled by the air sampling smoke detection sys-tem. A positive deviation indicates contamination in the sampled air. This can be remedied by inserting an air filter or, if possible, by switching to a lower sensitivity. Deposits of bright dirt particles inside the detection unit may lead to an increase in the reading. If the status reading does not im-prove after carrying out such measures, the detection unit must be repla-ced. A negative change is due to decreasing light output inside the detection unit. This can be caused by dirt in the optical chamber or dark dirt particle deposits inside the detection unit. If the detection unit status reading goes outside the permitted negative range, the detection unit should be changed.

8.9 Testing Air Flow Monitoring

A break or a blockage in a pipe are displayed on the diagnosis tool “Message” screen. Test air flow monitoring in accordance with the instructions described in Chapter 7 "Air Flow Monitoring".

8.10 Testing Fault Forwarding

A fault is displayed on the TITANUS RACK·SENS® 1U and possibly on the fire panel. Proceed as described in Chapter 7 "Fault Forwarding ".


8 – 10 Data: 03/09 TRS_A_08-en-e

8.11 Maintenance intervals

Maintenance includes carrying out regular inspections and servicing. Air sampling smoke detection systems are first tested during set-up opera-tions and then every three months.

If the TITANUS RACK·SENS® 1U is connected to a hazard alert system, the following tests are required in accordance with VDE (German Electri-cal Engineering Association) 0833:

quarterly check Inspection

annual check Servicing + inspection

If the TITANUS RACK·SENS® 1U is operated as a stand-alone device (not connected to a hazard alert system), servicing can take place at the operator’s discretion. However, it is recommended to carry out servicing every 18 months. Country-specific guidelines must be complied with at all times.
